WATER-M ETER.

SPECIFICATION formng part of Letters Patent No. 742,947, dated ovember3, 1903.

Application led August 23, 1900. Renewed April 8, 1903. Serial No.151,682. (No model.)

the accompanying drawings, forming a part of the same.

This invention relates generally to that class of meters for measuringthe quantity of iowing liquids which are known in the art aspiston-meters, but more particularly to a meter having the generalcharacteristics of the meter shown and described in Letters Patent No.13,320, dated July 24, 1855, and

p No. 338,972, dated March 30, 1886, consisting of two cylinders whichare provided with double-acting plungers and with induction anddischarge ports, which are so arranged that the induction and dischargevalves of each cylinder are operated by the plunger of the other,thereby causing the movement of each plunger to be controlled by theother, as fully described in the Letters Patent above referred to.

The object of the present invention is to improve the construction ofsuch liquid-meters and the invention relates especially to a novelconstruction of valves and valve-chambers by which the size and weightof the valvechamber may be reduced and the valve-seats and valves freedfrom foreign matter mor'e readily than in liquid-meters as heretoforeconstructed.

The invention includes also a plunger construction by which the lengthof the meter may be reduced andthe desired strength and lightness ofconstruction secured.

For a full understanding of the invention a detailed description of aconstruction embodying all the features of the invention as applied intheir preferred form in connection with a liquid-meter of the particularclass above referred to will now be given in connection with theaccompanying drawings, forming a part of this specification, and thefeatures forming the invention will then be speciically pointed out inthe claims.

In the drawings, Figure 1 is a central crosssection of the meter. Fig. 2is a longitudinal vertical section on the line 2 of Figs. l and 3. Fig.2EL is a similar partial section taken on line .2a of Fig. 1. Fig. 3 isa horizontal section or plan vof the valve-chamber on the line 3 ofFigs. 1 and 2. Fig. 4 is a longitudinal section on the line 4 of Fig. 3.Fig. 5 is a cross-section on either of the lines 5 of Fig. 3.

Referring to said drawings, the general arrangement and operation of themeter are the same as fully described in Letters Patent No. 338,972, themeter consisting of the two cylindersA A', forming the top of themeter,and the valve-chamber C, forming the base of the meter and containingthe ports and passages which lead from the valves to and from theopposite ends of the cylinders, induction-pipe D communicating with thisbase of the meter at one side and discharge-pipe E at the opposite sidecentrally of the meter lengthwise. The cylinders A A are provided withpacking-rings 10, through which' the plungersB B reciprocate andwhich,together with the plungers, form the four chambers at the ends ofthe cylinders. The cylinders are shown as provided at their oppositeends with removable heads 11, and the body portion of the meter has theusual central top opening 12 for the shaft of the registering mechanism.The plungers B B are preferably of the form shown clearly in Fig.` 2,being hollow and open at their ends, so that the length of the centralportion of the plungers is largely reduced below that of the closedplungers heretofore used.

These plungers are formed of the two end shells 13, having the centraldisks ,.3

14 and flanges 15, which-flanges move in the packing-rings 10, and thedisks 14 are provided With the projecting screw-flanges 16, by which thetwo ends are connected together byscrew-sleeve 17 to form the plungers.The disks 14 are provided with central bumpers 18, which engageinwardly-projecting buers 19 on heads l1, which are preferably rubber orother elastic buffers, held between narrow flanges oninwardly-projecting central portions 20 on heads 11, the buffers 19being held in place by screw-plugs 21. The ianges 15 ICQ thus enter thecircumferential spaces about the inwardly-projecting portions 2O ofheads 11 at the'end of the movement of the plungers, the desirable longbearing of the flanges and packing-rings lO thus being secured with ashort meter construction.

Below the plungers B B' are the valves G H; but these valves instead ofmoving on horizontal seats and being arranged directly under theplungers, as heretofore, are set somewhat inside the central line of theplungers, and the desired valve capacity is secured with the horizontalwidth of the valvechamber diminished by inciining the valves and theirseats 22, as shown in Fig. 1, the highest parts of the inclined seatsbeing adjacent and the seats and valvessloping downward and outwardtoward the opposite sides of the meter. The size of the base portion ofthe meter is thus reduced, and the incline aids also in keeping theseats and faces of the valves free from any foreign material that may becarried in the water and liable to deposit on the seats. These valves GH are shown as of substantially the same construction and operated bythe plungers B B' in the same manner as in Patent No. 338,972, abovereferred to, except that valve G is a D-valve and the other valve H is aB-valve, the valve and port arrangement therefore being such that theports do not cross each other, as in the Patent No. 338,972; but thecross-motion takes place in the valves, which provides for a simplermeter-bottom and enables it to be made shallower, while securing a largocapacity. Any increase in depth resulting from the inclining ot' thevalves is thnscompensated for. The valves G H have the usualupwardly-projecting operating-flanges 23, by which the valves are movedin opposite directions by the plungers B B', and are shown as providedwith guiding-ribs 24, moving between fixed guides 25 on' the valve-seatcasting 26, which casting is shown as formed separately from thebase-casting C and secured thereto by screws 1, although it will beunderstood that these parts may be constructed in any other suitablemanner.

The port construction of the casting C is as follows: The valve-seats 22are provided with induction-ports a ct and discharge-ports b b.' for therespective cylinders A A', these ports for each cylinder beingcontrolled by the corresponding valve actuated by the plunger on theopposite cylinder. These ports a d' and b' b' connect with the inductionand.l

discharge pipes D Eand the cylinders through passages in thebase-casting C, as follows: The induction-pipe D communicates throughpassage 27, which is at the side of the meter and b b' through thevalves G H. Ports a' for cylinder A', which ports are on the A cylinderside of the meter and controlled by valve G, actuated by the plunger B,connect with the chambers at the opposite ends of the plunger B' throughhorizontal passages 2S in the base C and vertical passages 29 in thebase and cylinder castings, and the ports ct for cylinder` A, whichports are on the A cylinder side of the meter and controlled by valve H,actuated by plunger B', communicate with the chambers at the oppositeends of the plunger B by passages 30 in base-casting C and Verticalpassages 31 in the base and cylinder castings. The passages 28 30,running across the base-casting C, are arranged with the passages 28above the passages 30, these passages being wide and shallow, so thatthe base-castingis correspondingly shallow, this being permitted by thefact that the passages for the opposite ends of each cylinder do notcross each other. 'I he discharge-port b' for cylinder A', which portalso is on the A cylinder side of the engine and controlled by valve G,communicates with the discharge-pipe E through discharge-passage 32,running across the center of the-basecasting C between the passages 2830, and the discharge-port b for cylinder A, which port is on the A'cylinder side of the engine and controlled by valve G,communicates withthe same discharge-passage 32.

It will be understood that modifications in v the construction shown maybe made Without departing from the invention, and I am not to be limitedto the exact form or arrangement of parts illustrated. The feature ofinclined valve-seats and valves is applicable generally in meters andsimilar apparatus having two cylinders arranged side by side and is thusclaimed.

1. The combination with two cylinders arranged side by side, of valvesarranged to move longitudinally of the cylinders and valve-seatsarranged side by side and on opposite sides of a plane central betweenthe cylinders, and inclined transversely to the cylinders, substantiallyas described.

2. The combination Withthe two cylinders IOO IIOl

A, A' and their plungers B, B', of the base l yseats arranged to movelongitudinally of the cylinders, substantially as described.

3. The combinationwith the two cylinders A, A' and their plungers B, B',of the base portion having the valve-seats 2 2 arranged `vopposite thespace between the plungers and inclined downward and outward in oppositedirections transversely to the'cylinders, and valves on said seats,substantially as described.

4. The combination with the two cylinders A, A' and their plungers B,B', of `the base portion having valve-seats 22 inclined transversely tethe cylinders, and valves on said seats, one of said valves being aB-valve and the other a. D-valve, and admission-ports to the oppositeends of said cylinders controlled by said valves, substantially asdescribed.

5. A plunger formed of the head-shells 13 having.,r projectingrim-flanges 15 and central fianges 16, of cent-ral sleeve 17 secured tosaid l flanges and connecting the shells, substan- Ie tially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
